Abstract
BACKGROUND Umbilical cord blood transplant (UCBT) improves access to transplant for patients lacking a fully matched donor. Previous Center for International Blood and Marrow Transplant Research (CIBMTR) showed that Black patients had a lower overall survival (OS) than White patients following single UCBT. The current study draws on a larger modern cohort and compares outcomes among White, Latinx, Black, and Asian patients. OBJECTIVE To compare outcomes by social determinants of health. STUDY DESIGN We designed a retrospective study using CIBMTR data. US patients were between ages 1 and 80; 983 received single and 1529 double UCBT as reported to CIBMTR, following either a myeloablative (N = 1752) or reduced intensity conditioning (N = 759) for acute myeloid leukemia, acute lymphoid leukemia, or myelodysplasia. The primary outcome was 2-year OS. Secondary outcomes included disease free survival, transplant related mortality (TRM), acute and chronic graft vs host disease (GVHD), and GVHD free, relapse free survival (GRFS). RESULTS For 1705 adults, in univariate analysis, 2-year OS was 41.5% (99% CI, 37.6 to 45.3) for Whites, 36.1% (99% CI, 28.2 to 44.5) for Latinx, 45.8% (99% CI, 36.7 to 55.1) for Blacks, and 44.5% (99% CI, 33.6 to 55.6) for Asians. In multivariate analysis of adults, Latinx patients had inferior OS compared to black patients (p = .0005, HR 1.45, 99% CI 1.18 to 1.79). OS improved over time for all racial/ethnic groups. GVHD rates were comparable among the different racial/ethnic groups. In the 807 children, the 2-year OS in univariate analysis was 66.1% (99% CI, 59.7 to 72.2) for Whites, 57.1% (99%CI, 49 to 64.9) for Latinx, 46.8% (99%CI, 35.3 to 58.4) for Blacks, and 53.8% (99%CI, 32.7 to 74.2) for Asians. In multivariate analysis, no difference in OS was observed among racial/ethnic groups (p = .051). Grade III/IV acute GVHD was higher in Blacks compared with Whites (p = .0016, HR 2.25, 99% CI 1.36 to 3.74) and Latinx (p = .0016, HR 2.17, 99% CI 1.43 to 3.30). There was no survival advantage to receiving a UCB unit from a donor of similar race and ethnicity, for any racial/ethnic groups, for both children and adults. Black and Latinx adult patients were more likely to live in areas defined as high poverty. Patients from high poverty level areas had worse OS (p = .03), due to a higher rate of TRM (p=0.04). Educational level, and type of insurance did not impact overall survival, GVHD, TRM or other transplant outcomes. Children from areas with a higher poverty level had higher TRM, regardless of race and ethnicity (p = .02). Public health insurance, such as Medicaid, was also associated with a higher TRM (p = .02). However, poverty did not impact pediatric OS, DFS, or other post-transplant outcomes. CONCLUSIONS OS for UCBT has improved over time. In adults, OS is comparable among Whites, Blacks, and Asians and lower for Latinx patients. In children, OS is comparable among Whites, Blacks, Latinx, and Asians, but Grade III/IV acute GVHD was higher in Black patients. There was no survival benefit to matching UCB unit and patient by race and ethnicity for adults and children.

Abstract
ABSTRACT There has been an increase in volume as well as an improvement in overall survival (OS) after hematopoietic cell transplantation (HCT) for hematologic disorders. It is unknown if these changes have affected racial/ethnic minorities equally. In this observational study from the Center for International Blood and Marrow Transplant Research of 79 904 autologous (auto) and 65 662 allogeneic (allo) HCTs, we examined the volume and rates of change of autoHCT and alloHCT over time and trends in OS in 4 racial/ethnic groups: non-Hispanic Whites (NHWs), non-Hispanic African Americans (NHAAs), and Hispanics across 5 2-year cohorts from 2009 to 2018. Rates of change were compared using Poisson model. Adjusted and unadjusted Cox proportional hazards models examined trends in mortality in the 4 racial/ethnic groups over 5 study time periods. The rates of increase in volume were significantly higher for Hispanics and NHAAs vs NHW for both autoHCT and alloHCT. Adjusted overall mortality after autoHCT was comparable across all racial/ethnic groups. NHAA adults (hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.04-1.22; P = .004) and pediatric patients (HR 1.62; 95% CI 1.3-2.03; P < .001) had a higher risk of mortality after alloHCT than NHWs. Improvement in OS over time was seen in all 4 groups after both autoHCT and alloHCT. Our study shows the rate of change for the use of autoHCT and alloHCT is higher in NHAAs and Hispanics than in NHWs. Survival after autoHCT and alloHCT improved over time; however, NHAAs have worse OS after alloHCT, which has persisted. Continued efforts are needed to mitigate disparities for patients requiring alloHCT.

Social determinants of health predict health outcomes following pediatric allogeneic hematopoietic stem cell transplant. Pediatr Blood Cancer 2024; 71:e30892.

Abstract
BACKGROUND Pediatric hematopoietic stem cell transplantation (HCT) is an intensive medical procedure that places substantial financial and logistical burdens on families and is associated with significant health risks, such as graft-versus-host disease (GVHD), and infections. The influence of the social determinants of health (SDoH) on outcomes following pediatric HCT is understudied. This study aimed to examine whether SDoH predicts outcomes following pediatric HCT. PROCEDURE Data were collected from 84 children who received HCT (Mage = 5.8 years, SD = 3.7) and their primary caregiver. Detailed demographic information was collected from caregivers at baseline, and child health information was extracted from the electronic medical records. Multivariate logistic regression was used to examine the association between SDoH and health outcomes within a 24-month period following pediatric HCT. RESULTS After controlling for malignancy as reason for transplant and donor type, lower family income predicted the incidence of chronic GVHD. Neighborhood deprivation, total family income, public health insurance, caregiver relationship status, caregiver educational attainment, and perceived family financial difficulties did not predict acute GVHD or the number of infections. CONCLUSIONS Total family income is a simple family indicator of SDoH that predicts chronic GVHD after pediatric allogeneic HCT. These findings provide further support for the importance of screening of child and family SDoH risks to ensure that fundamental needs can be met to mitigate potential health disparities for up to 2 years following pediatric HCT.

Abstract
ABSTRACT Allogeneic hematopoietic cell transplantation (HCT) can be complicated by life-threatening organ toxicity and infection necessitating intensive care. Epidemiologic data have been limited by single-center studies, poor database granularity, and a lack of long-term survivors. To identify contemporary trends in intensive care unit (ICU) use and long-term outcomes, we merged data from the Center for International Blood and Marrow Transplant Research and the Virtual Pediatric Systems databases. We identified 6995 pediatric patients with HCT aged ≤21 years who underwent first allogeneic HCT between 2008 and 2014 across 69 centers in the United States or Canada and followed patients until the year 2020. ICU admission was required for 1067 patients (8.3% by day +100, 12.8% by 1 year, and 15.3% by 5 years after HCT), and was linked to demographic background, pretransplant organ toxicity, allograft type and HLA-match, and the development of graft-versus-host disease or malignancy relapse. Survival to ICU discharge was 85.7%, but more than half of ICU survivors required ICU readmission, leading to 52.5% and 42.6% survival at 1- and 5-years post-ICU transfer, respectively. ICU survival was worse among patients with malignant disease, poor pretransplant organ function, and alloreactivity risk factors. Among 1-year HCT survivors, those who required ICU in the first year had 10% lower survival at 5 years and developed new dialysis-dependent renal failure at a greater rate (P<.001). Thus, although ICU management is common and survival to ICU discharge is high, ongoing complications necessitate recurrent ICU admission and lead to a poor 1-year outcome in select patients who are at high risk.

[PMID: 37921440 PMCID: PMC11008006 DOI: 10.1158/1055-9965.epi-23-0801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 10/16/2023] [Accepted: 11/01/2023] [Indexed: 11/04/2023] Open
Abstract
BACKGROUND Tobacco smoke adversely affects the prognosis of adult cancers including myeloid leukemia, but less is known in children. METHODS We evaluated whether pre- and postnatal exposures to tobacco smoke decrease 5-year survival of 1,235 childhood acute lymphoblastic leukemia (ALL) and 188 childhood acute myeloid leukemia (AML) cases derived from a population-based case-control study in California. Cases were diagnosed between 1995 and 2015 (median follow-up time of 13.2 years overall). We obtained data on tobacco smoking (before conception, during pregnancy, after birth), parental education and income, clinical features, and vital status through 2020. Cox proportional hazards regression was used to calculate hazard ratios (HR) and 95% confidence intervals (CI) for mortality associated with smoking, adjusting for sociodemographic characteristics and risk group (ALL only). RESULTS About 23% of mothers and 39% of fathers reported smoking and 130 children with ALL and 52 with AML died within 5 years. For AML, increased risks of death were observed among children whose fathers smoked before conception compared with nonsmoking fathers [HR = 1.41; 95% confidence interval (CI), 0.95-3.44 and 3.47; 95% CI, 1.37-8.81, respectively for <20 vs. ≥20 cigarettes per day; Ptrend = 0.01]. HR for child's passive smoking was 1.74, 95% CI, 0.81-3.73. Paternal preconception smoking may also reduce 5-year survival among ALL with favorable prognostic molecular subtypes (high hyperdiploidy and absence of IKZF1 gene deletion), although the associations did not reach statistical significance (Pheterogeneity = 0.07). CONCLUSIONS Paternal preconception smoking decreased 5-year survival of childhood AML. IMPACT Knowledge of exposure to tobacco smoking should be integrated in the treatment plan of childhood leukemias.

Abstract
The American Society for Transplantation and Cellular Therapy (ASTCT) and the National Marrow Donor Program (NMDP) formed the ACCESS Initiative to address and reduce barriers to hematopoietic cell transplantation (HCT) and cellular therapy (CT) to ensure equal access and outcomes for all patients in need. The 3 committees, addressing awareness, poverty, and racial and ethnic inequity, defined pilot projects focusing on addressing relevant barriers to HCT/CT. Because many socioeconomically disadvantaged HCT/CT recipients receive care through state Medicaid programs, the Poverty Committee conducted a Medicaid scan of all 50 US states with the following objectives: to define beneficiary coverage for allogeneic and autologous HCT and chimeric antigen receptor (CAR) T cell therapy; to define support for travel, temporary lodging, and meals for both beneficiaries and caregivers; and to determine search and cell acquisition payment procedures. Here we summarize the results of the Medicaid scan and highlight significant variations and gaps in coverage for HCT/CT recipients. We also provide an initial roadmap for addressing gaps in Medicaid support for HCT and CAR-T therapy recipients.

Racial and Socioeconomic Disparities in Long-Term Outcomes in ≥1 Year Allogeneic Hematopoietic Cell Transplantation Survivors: A CIBMTR Analysis. Transplant Cell Ther 2023; 29:709.e1-709.e11. [PMID: 37482244 PMCID: PMC11258715 DOI: 10.1016/j.jtct.2023.07.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 07/10/2023] [Accepted: 07/14/2023] [Indexed: 07/25/2023]
Abstract
Racial/ethnic minorities have demonstrated worse survival after allogeneic hematopoietic cell transplantation (HCT) compared to whites. Whether the racial disparity in HCT outcomes persists in long-term survivors and possibly may be even exacerbated in this population, which frequently transitions back from the transplant center to their local healthcare providers, is unknown. In the current study, we compared long-term outcomes among 1-year allogeneic HCT survivors by race/ethnicity and socioeconomic status (SES). The Center for International Blood and Marrow Transplant Research database was used to identify 5473 patients with acute myeloid leukemia, acute lymphocytic leukemia, chronic myeloid leukemia, or myelodysplastic syndromes who underwent their first allogeneic HCT between 2007 and 2017 and were alive and in remission for at least 1 year after transplantation. The study was restricted to patients who underwent HCT in the United States. SES was defined using patient neighborhood poverty level estimated from the recipient's ZIP code of residence; a ZIP code with ≥20% of persons below the federal poverty level was considered a high poverty area. The primary outcome was to evaluate the associations of race/ethnicity and neighborhood poverty level with overall survival (OS), relapse, and nonrelapse mortality (NRM). Cox regression models were used to determine associations of ethnicity/race and SES with OS, relapse, and NRM. Standardized mortality ratios were calculated to compare mortality rates of the study patients and their general population peers matched on race/ethnicity, age, and sex. The study cohort was predominately non-Hispanic white (n = 4385) and also included non-Hispanic black (n = 338), Hispanic (n = 516), and Asian (n = 234) patients. Overall, 729 patients (13%) resided in high-poverty areas. Significantly larger proportions of non-Hispanic black (37%) and Hispanic (26%) patients lived in high-poverty areas compared to non-Hispanic whites (10%) and Asians (10%) (P < .01). Multivariable analysis revealed no significant associations between OS, PFS, relapse, or NRM and race/ethnicity or poverty level when adjusted for patient-, disease- and transplantation-related covariates. Our retrospective cohort registry study shows that among adult allogeneic HCT recipients who survived at least 1 year in remission, there were no associations between race/ethnicity, neighborhood poverty level, and long-term outcomes.

Abstract
Background Allogeneic hematopoietic cell transplantation (HCT) can be complicated by the development of organ toxicity and infection necessitating intensive care. Risk factors for intensive care admission are unclear due to heterogeneity across centers, and long-term outcome data after intensive care are sparse due to a historical paucity of survivors. Methods The Center for International Blood and Marrow Transplant Research (CIBMTR) was queried to identify patients age ≤21 years who underwent a 1st allogeneic HCT between 2008-2014 in the United States or Canada. Records were cross-referenced with the Virtual Pediatric Systems pediatric ICU database to identify intensive care admissions. CIBMTR follow-up data were collected through the year 2020. Result We identified 6,995 pediatric HCT patients from 69 HCT centers, of whom 1,067 required post-HCT intensive care. The cumulative incidence of PICU admission was 8.3% at day +100, 12.8% at 1 year, and 15.3% at 5 years post HCT. PICU admission was linked to younger age, lower median zip code income, Black or multiracial background, pre-transplant organ toxicity, pre-transplant CMV seropositivity, use of umbilical cord blood and/or HLA-mismatched allografts, and the development of post-HCT graft-versus-host disease or malignancy relapse. Among PICU patients, survival to ICU discharge was 85.7% but more than half of ICU survivors were readmitted to a PICU during the study interval. Overall survival from the time of 1st PICU admission was 52.5% at 1 year and 42.6% at 5 years. Long-term post-ICU survival was worse among patients with malignant disease (particularly if relapsed), as well as those with poor pre-transplant organ function and alloreactivity risk-factors. In a landmark analysis of all 1-year HCT survivors, those who required intensive care in the first year had 10% lower survival at 5 years (77.1% vs. 87.0%, p<0.001) and developed new dialysis-dependent renal failure at a greater rate (p<0.001). Conclusions Intensive care management is common in pediatric HCT patients. Survival to ICU discharge is high, but ongoing complications necessitate recurrent ICU admission and lead to a poor 1-year outcome in many patients. Together, these data suggest an ongoing burden of toxicity in pediatric HCT patients that continues to limit long-term survival.

Abstract
The treatment of malignant and nonmalignant hematologic disorders continues to benefit from significant scientific advancement and progress in the use of hematopoietic cell transplantation and cellular therapies. However, barriers associated with receiving these lifesaving treatments and care remain, which necessitate innovative approaches to overcome, so all persons in need can receive these therapies. This article reviews barriers to receiving hematopoietic cell transplantation and cellular therapies, and highlights novel approaches taken by the National Marrow Donor Program in reducing barriers for all patients in need.

Abstract
Introduction Social determinants of health (SDOH) are important contributors to health outcomes, and better understanding their impact on individuals diagnosed with rare, chronic diseases with high burden and unmet need is critical. Characterizing SDOH burden can help improve the design of patient support programs (PSPs), using targeted approaches to remove barriers to access. Methods This study used a mixed-methods strategy employing a quantitative survey, which was designed based on qualitative interviews, to understand the unmet needs and awareness/utilization of PSPs among individuals living with generalized myasthenia gravis (gMG) and experiencing SDOH barriers. The survey was completed by 38 individuals living with gMG, of which the majority were non-White/Caucasian, unemployed, low income, and enrolled in public insurance. Common SDOH challenges, awareness/utilization of available PSPs, and unmet needs were identified. Results Financial and mental health concerns were the most common among individuals living with gMG and experiencing SDOH barriers throughout diagnosis, accessing treatment, initiating treatment, and continuing treatment. Awareness and utilization of existing support services were low, especially when accessing treatment. Educational, financial, and personalized support with high "human touch" were commonly perceived as the most valuable resources. Implications To better serve the needs of individuals with gMG experiencing SDOH barriers, PSPs should use a targeted approach to offer services tailored to harder-to-reach populations. Further, providers, advocacy groups, manufacturers, and public organizations in the gMG ecosystem should strengthen collaborations with PSPs to enable individuals living with gMG to access the services they need to improve their health outcomes.

Abstract
Neighborhood socioeconomic deprivation may have important implications on disparities in liver transplant (LT) evaluation. In this retrospective cohort study, we constructed a novel dataset by linking individual patient-level data with the highly granular Area Deprivation Index (ADI), which is advantageous over other neighborhood measures due to: specificity of Census Block-Group (versus Census Tract, Zip code), scoring, and robust variables. Our cohort included 1377 adults referred to our center for LT evaluation 8/1/2016-12/31/2019. Using modified Poisson regression, we tested for effect measure modification of the association between neighborhood socioeconomic status (nSES) and LT evaluation outcomes (listing, initiating evaluation, and death) by race and ethnicity. Compared to patients with high nSES, those with low nSES were at higher risk of not being listed (aRR = 1.14; 95%CI 1.05-1.22; p < .001), of not initiating evaluation post-referral (aRR = 1.20; 95%CI 1.01-1.42; p = .03) and of dying without initiating evaluation (aRR = 1.55; 95%CI 1.09-2.2; p = .01). While White patients with low nSES had similar rates of listing compared to White patients with high nSES (aRR = 1.06; 95%CI .96-1.17; p = .25), Underrepresented patients from neighborhoods with low nSES incurred 31% higher risk of not being listed compared to Underrepresented patients from neighborhoods with high nSES (aRR = 1.31; 95%CI 1.12-1.5; p < .001). Interventions addressing neighborhood deprivation may not only benefit patients with low nSES but may address racial and ethnic inequities.

Abstract
Chimeric antigen receptor T cell (CAR-T) therapy is a promising approach to improve survival for children and adults with relapsed/refractory (r/r) B cell acute lymphoblastic leukemia (B-ALL), but these clinical trials might not be equally accessible to patients of low socioeconomic status (SES) or to patients from racial or ethnic minority groups. We sought to describe the sociodemographic characteristics of pediatric and adolescent and young adult (AYA) patients enrolled in CAR-T clinical trials and to compare these characteristics to those of other patients with r/r B-ALL. We conducted a multicenter retrospective cohort study at 5 pediatric consortium sites to compare the sociodemographic characteristics of patients treated and enrolled in CAR-T trials at their home institution, other patients with r/r B-ALL treated at these sites, and patients referred from an external hospital for CAR-T trials. The patients were age 0 to 27 years with r/r B-ALL treated at 1 of the consortium sites between 2012 and 2018. Clinical and demographic data were collected from the electronic health record. We calculated distance from home to treating institution and assigned SES scores based on census tract. Among the 337 patients treated for r/r B-ALL, 112 were referred from an external hospital to a consortium site and enrolled in a CAR-T trial and 225 were treated primarily at a consortium site, with 34% enrolled in a CAR-T trial. Patients treated primarily at a consortium site had similar characteristics regardless of trial enrollment. Lower proportions of Hispanic patients (37% versus 56%; P = .03), patients whose preferred language was Spanish (8% versus 22%; P = .006), and publicly insured patients (38% versus 65%; P = .001) were referred from an external hospital than were treated primarily at a consortium site and enrolled in a CAR-T trial. Patients who are Hispanic, Spanish-speaking, or publicly insured are underrepresented in referrals from external hospitals to CAR-T centers. External provider implicit bias also may influence referral of these patients. Establishing partnerships between CAR-T centers and external hospital sites may improve provider familiarity, patient referral, and patient access to CAR-T clinical trials.

Hoppmann AL, Dai C, Daves M, Imran H, Whelan K, Kenzik K, Bhatia S. Persistent Child Poverty and Mortality in a Cohort of Children with Cancer in Alabama. Cancer Epidemiol Biomarkers Prev 2023; 32:380-386. [PMID: 36129811 PMCID: PMC9991934 DOI: 10.1158/1055-9965.epi-22-0353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 05/27/2022] [Accepted: 09/13/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND One-fifth of U.S. counties are designated persistent child poverty counties (≥20% of children in poverty since 1980). The association between a persistent child poverty environment and mortality in children with cancer is unknown. METHODS Our cohort includes 2,089 children with cancer (2000-2016) in Alabama. We used multivariable Cox proportional hazards modeling (adjusted for sociodemographics/clinical characteristics) to assess mortality by persistent child poverty designation at 1, 5, and 10 years from diagnosis. Distance to treatment was subsequently explored. RESULTS Forty-two percent of the cohort lived in a persistent child poverty county; they were more likely to be African American (P < 0.0001), have public/no insurance (P = 0.0009), and live >100 miles to treatment (P < 0.0001). Children in persistent child poverty counties were 30% more likely to die by 5 years [95% confidence interval (CI) = 1.06-1.59; P = 0.012]. Distance (per 20-mile increase) to treatment was associated with a 9% increased mortality risk (P < 0.0001). Children with both exposures (distance >100 miles and persistent child poverty) faced the highest mortality risk at 5 years (HR = 1.80; 95% CI = 1.39-2.33; P < 0.0001). In subanalysis, children exposed to persistent child poverty were at higher risk for cancer-related mortality. However, the risk of health-related mortality did not differ. CONCLUSIONS Among children with cancer from the Deep South, persistent child poverty was a prevalent exposure associated with inferior overall survival. Distance to treatment was independently associated with inferior survival. Children with both exposures had the highest risk of mortality. IMPACT Persistent child poverty is associated with inferior survival among children with cancer; mechanisms underlying this disparity warrant investigation.

Abstract
Children living in poverty experience excessive relapse and death from newly diagnosed acute lymphoblastic leukemia (ALL). The influence of household poverty and neighborhood social determinants on outcomes from chimeric antigen receptor (CAR) T-cell therapy for relapsed/refractory (r/r) leukemia is poorly described. We identified patients with r/r CD19+ ALL/lymphoblastic lymphoma treated on CD19-directed CAR T-cell clinical trials or with commercial tisagenlecleucel from 2012 to 2020. Socioeconomic status (SES) was proxied at the household level, with poverty exposure defined as Medicaid-only insurance. Low-neighborhood opportunity was defined by the Childhood Opportunity Index. Among 206 patients aged 1 to 29, 35.9% were exposed to household poverty, and 24.9% had low-neighborhood opportunity. Patients unexposed to household poverty or low-opportunity neighborhoods were more likely to receive CAR T-cell therapy with a high disease burden (>25%), a disease characteristic associated with inferior outcomes, as compared with less advantaged patients (38% vs 30%; 37% vs 26%). Complete remission (CR) rate was 93%, with no significant differences by household poverty (P = .334) or neighborhood opportunity (P = .504). In multivariate analysis, patients from low-opportunity neighborhoods experienced an increased hazard of relapse as compared with others (P = .006; adjusted hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.3-4.1). There was no difference in hazard of death (P = .545; adjusted HR, 1.2; 95% CI, 0.6-2.4). Among children who successfully receive CAR T-cell therapy, CR and overall survival are equitable regardless of proxied SES and neighborhood opportunity. Children from more advantaged households and neighborhoods receive CAR T-cell therapy with a higher disease burden. Investigation of multicenter outcomes and access disparities outside of clinical trial settings is warranted.

Abstract
The American Society for Transplantation and Cellular Therapy (ASTCT) and the National Marrow Donor Program (NMDP) have formed the ACCESS Initiative to address and reduce barriers to hematopoietic cell transplantation (HCT) and cellular therapy (CT) in an effort to ensure equal access and outcomes for all patients in need. In addition to cellular therapy physicians, the initiative includes program administrators, health policy and health equity experts, health service researchers, participants from commercial payer organizations, and federal stakeholders. The inaugural ASTCT-NMDP ACCESS Workshop was held in Washington, DC on July 28 and 29, 2022, wherein committee members met to discuss and to define goals for 3 focus areas: awareness, poverty, and racial and ethnic inequity. This position paper reviews the mission, vision, and structure of the ACCESS Initiative and the proceedings from the inaugural workshop and provides an initial roadmap for the group's efforts at reducing access barriers and outcome disparities in HCT/CT.

Abstract
Severe acute and chronic graft versus host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic cell transplantation. Historically, cord blood and matched sibling transplantation has been associated with the lowest rates of GVHD. Newer methods have modified the lymphocyte components to minimize alloimmunity, including: anti-thymocyte globulin, post-transplant cyclophosphamide, alpha/beta T cell depletion, and abatacept. These agents have shown promise in reducing severe GVHD, however, can be associated with increased risks of relapse, graft failure, infections, and delayed immune reconstitution. Nonetheless, these GVHD prophylaxis strategies have permitted expansion of donor sources, especially critical for those of non-Caucasian decent who previously lacked transplant options. This review will focus on the biologic mechanisms driving GVHD, the method by which each agent impacts these activated pathways, and the clinical consequences of these modern prophylaxis approaches. In addition, emerging novel targeted strategies will be described. These GVHD prophylaxis approaches have revolutionized our ability to increase access to transplant and have provided important insights into the biology of GVHD and immune reconstitution.

Social Vulnerability and Risk of Nonrelapse Mortality After Allogeneic Hematopoietic Cell Transplantation. J Natl Cancer Inst 2022; 114:1484-1491. [PMID: 35980163 PMCID: PMC9664181 DOI: 10.1093/jnci/djac150] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 05/27/2022] [Accepted: 07/06/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Risk of nonrelapse mortality (NRM) after hematopoietic cell transplantation (HCT) is high. Patient-level clinical prediction models such as the HCT-comorbidity index (HCT-CI) help identify those at increased risk for NRM, but the independent contribution of social determinants of health on HCT outcomes is not well characterized. METHODS This study included 1602 patients who underwent allogeneic HCT between 2013 and 2019 at City of Hope. Census tract-level social vulnerability was measured using the social vulnerability index (SVI). Fine-Gray multivariable regression evaluated the association between SVI and 1-year NRM. Subgroup analysis examined risk of NRM across combined SVI and HCT-CI categories and by race and ethnicity. RESULTS Cumulative incidence of 1-year NRM after HCT was 15.3% (95% confidence interval [CI] = 13.6% to 17.1%). In multivariable analysis, patients in the highest SVI tertile (highest social vulnerability) had a 1.4-fold risk (subdistribution hazard ratio [sHR] = 1.36, 95% CI = 1.04 to 1.78) of NRM compared with individuals in the lower tertiles; patients in the highest SVI tertile who also had elevated (≥3) HCT-CI scores had the highest risk (sHR = 1.81, 95% CI = 1.26 to 2.58) of 1-year NRM (reference: lower SVI tertiles and HCT-CI < 3). High social vulnerability was associated with risk of 1-year NRM in Asian (sHR = 2.03, 95% CI = 1.09 to 3.78) and Hispanic (sHR = 1.63, 95% CI = 1.04 to 2.55) but not non-Hispanic White patients. CONCLUSIONS High social vulnerability independently associated with 1-year NRM after HCT, specifically among minority populations and those with a high comorbidity burden at HCT. These findings may inform targeted approaches for needs assessment during and after HCT, allowing for timely interventions to improve health outcomes in at-risk patients.

Enhancing Administrative Claims Data: Feasibility, Validation and Application of Linking Medicare Claims Data and National Marrow Donor Program Search Data. JCO Clin Cancer Inform 2022; 6:e2200069. [PMID: 36228178 PMCID: PMC9848571 DOI: 10.1200/cci.22.00069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 06/22/2022] [Accepted: 08/26/2022] [Indexed: 01/21/2023] Open
Abstract
PURPOSE Administrative claims data provide real-world service utilization of acute myeloid leukemia (AML) treatment, but lacks insight into treatment delays or barriers. The National Marrow Donor Program (NMDP)/Be The Match Search (Search) data contains information on donor search, but lacks information on treatment received if allogeneic hematopoietic cell transplant (HCT) is not performed. We hypothesized that linking these two data sets would create a rich resource to define factors associated with receiving HCT that could not be evaluated with either data set alone. METHODS A subset of 2010-2016 Medicare administrative claims data was linked with Search data. A total of 5,351 patients with AML age 65-74 years (HCT = 607, no HCT = 4,744) were identified using Medicare. These patients were then linked to 93,800 records with a donor search between 2009 and 2016. Patient date of birth, sex, disease, ZIP code, transplant center/hospital, and diagnosis date were used for matching. Exploratory analysis was conducted to identify predictors associated with receiving HCT for patients with AML who received a search. RESULTS The data sets were successfully linked, showing high sensitivity and specificity. The final cohort included 5,085 patients with AML (HCT = 533, no HCT = 4,552). Of 97 patients who received HCT without a matched search, more than 85% received a related donor HCT. Of those not receiving HCT, 609 had a matched NMDP search and 3,943 did not have a matched NMDP search. Multivariate analysis showed time to search, age, diagnosis year, race/ethnicity, and neighborhood education status associated with receiving HCT. CONCLUSION Methods herein demonstrate the feasibility of linking Search and Medicare data. Similar methods may be applied to answer critical questions regarding barriers to HCT, thereby identifying areas to improve access to care.

Abstract
BACKGROUND The excellent results of posttransplant cyclophosphamide in decreasing graft-versus-host disease (GVHD) after haploidentical (HI) allogeneic transplant have challenged current donor selection algorithms. PATIENTS AND METHODS We compared outcomes after matched sibling (MSD) versus alternative donor transplant using identical graft-versus-host disease (GVHD) prophylaxis including posttransplant cyclophosphamide (PTCy. Endpoints included engraftment, time outside of the hospital in the first 100 days after transplant, overall survival (OS), non-relapse mortality (NRM) and percentage of patients disease-free and off immunosuppression (DFOI) at one year and at the last follow-up. RESULTS There were significant differences at baseline between matched donor versus HI donor transplants with higher disease-risk index (DRI), more female-to-male donor recipient pairs and a higher percentage of Black patients in the HI group. Engraftment and time out of the hospital favored MSD and matched unrelated donor transplants. Multivariate analysis showed that high DRI and Black race were associated with decreased survival and Black race was associated with a higher NRM. CONCLUSIONS With the use of PTCy, our results support current donor selection algorithms. The finding of decreased survival and increased NRM in Black patients requires confirmation in a larger number of patients as well as the development of mitigation strategies.

Abstract
Despite treatment advancements and improved survival, approximately 1800 children in the United States will die of cancer annually. Survival may depend on nonclinical factors, such as economic stability, neighborhood and built environment, health and health care, social and community context, and education, otherwise known as social determinants of health (SDoH). Extant literature reviews have linked socioeconomic status (SES) and race to disparate outcomes; however, these are not inclusive of all SDoH. Thus, we conducted a systematic review on associations between SDoH and survival in pediatric cancer patients. Of the 854 identified studies, 25 were included in this review. In addition to SES, poverty and insurance coverage were associated with survival. More studies that include other SDoH, such as social and community factors, utilize prospective designs, and conduct analyses with more precise SDoH measures are needed.

Abstract
Survival disparities in children and adolescents with acute myeloid leukemia (AML) are documented, however, the etiology of these disparities is understudied. Few studies have evaluated factors that predict in-hospital mortality in childhood AML and racial/ethnic disparities associated with in-hospital death. Our study aimed to investigate factors associated with the risk of in-hospital death among childhood AML hospitalizations. We conducted a retrospective study of childhood AML hospitalizations using the National Inpatient Sample (NIS) from 2003 to 2017. We estimated incidences of in-hospital death among AML hospitalizations. We performed survey logistic regression models to measure the association between patient and hospital characteristics and in-hospital mortality. We identified 71,050 hospitalizations of children with AML. Compared with non-Hispanic (NH) whites, NH-black children had a higher risk of in-hospital mortality (adjusted odds ratio: 1.41, 95% confidence interval: 1.06-1.87, P<0.02). Further, NH-black patients with hematopoietic stem cell transplant experienced the highest risk of mortality (adjusted odds ratio: 5.88, 95% confidence interval: 3.13-11.06, P<0.001) as compared with NH-black children who did not receive hematopoietic stem cell transplant. Our findings highlight that NH-black children with AML continue to experience a disproportionately higher likelihood of in-hospital mortality when compared with their NH-white counterparts. Further studies are needed to delineate the etiology of these disparities.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) is particularly susceptible to racial, socioeconomic, and geographic disparities in access and outcomes given its specialized nature and its availability in select centers in the United States. Nearly all patients who need HCT have a potential donor in the current era, but racial minority populations are less likely to have an optimal donor and often rely on alternative donor sources. Furthermore, prevalent health care disparity factors are further accentuated and can be barriers to access and referral to a transplant center. Research has primarily focused on defining and quantifying a variety of social determinants of health and their association with access to allogeneic HCT, with a focus on race/ethnicity and socioeconomic status. However, research on interventions is lacking and is an urgent unmet need. We discuss the role of racial, socioeconomic, and geographic disparities in access to allogeneic HCT, along with policy changes to address and mitigate them and opportunities for future research.

Abstract
Allogeneic hematopoietic cell transplantation (allo-HCT) is a highly complex, costly procedure for patients with oncologic, hematologic, genetic, and immunologic diseases. Demographics and socioeconomic status as well as donor availability and type of health care system are important factors that influence access to and outcomes following allo-HCT. The last decade has seen an increase in the numbers of allo-HCTs and teams all over the world, with no signs of saturation. More than 80 000 procedures are being performed annually, with 1 million allo-HCTs estimated to take place by the end of 2024. Many factors have contributed to this, including increased numbers of eligible patients (older adults with or without comorbidities) and available donors (unrelated and haploidentical), improved supportive care, and decreased early and late post-HCT mortalities. This increase is also directly linked to macro- and microeconomic indicators that affect health care both regionally and globally. Despite this global increase in the number of allo-HCTs and transplant centers, there is an enormous need for increased access to and improved outcomes following allo-HCT in resource-constrained countries. The reduction of poverty, global economic changes, greater access to information, exchange of technologies, and use of artificial intelligence, mobile health, and telehealth are certainly creating unprecedented opportunities to establish collaborations and share experiences and thus increase patient access to allo-HCT. A specific research agenda to address issues of allo-HCT in resource-constrained settings is urgently warranted.

Abstract
PURPOSE OF REVIEW To discuss the clinical experience of coronavirus disease 2019 (COVID-19) in hematopoietic cell transplant and chimeric antigen receptor T-cell therapy recipients over the past year and to identify key knowledge gaps for future research. RECENT FINDINGS Immunocompromised individuals and those with chronic health conditions are especially susceptible to infections, which have had a disproportionate impact on health outcomes during the COVID-19 pandemic. Several studies have evaluated the clinical characteristics and outcomes of transplant and cellular therapy (TCT) recipients who developed COVID-19. Age, sex, comorbid conditions, and social determinants of health are important predictors of the risk of severe acute respiratory syndrome coronavirus 2 infection and of the eventual severity of the disease. Various treatment approaches have been investigated over the last year. The paradigm of management strategies continues to evolve as more experience is accumulated. SUMMARY In this review, we summarize some important findings as they relate to the clinical characteristics of TCT recipients who develop COVID-19. We also discuss some treatment approaches that are currently recommended and opine on vaccination in this population.

Abstract
OBJECTIVE Inborn errors of immunity (IEI) are rare genetic conditions affecting the immune system. The rate of IEI and their presentation, course, and treatment are all affected by a multitude of social determinants, eventually affecting prognosis. This review summarizes the current knowledge of the social determinants affecting infectious susceptibility, genetic predisposition, diagnosis, and treatment of IEI. DATA SOURCES PubMed. STUDY SELECTIONS Search terms included "consanguinity," "social determinants," and "founder effect." Further studies were selected based on relevant citations. RESULTS Changes in climate and human behavior have modulated the spread of disease vectors and infectious organisms. Consanguinity increases the rate of autosomal recessive conditions, changes the distribution, and affects the severity of IEI. Access to sophisticated genetic and immunologic diagnostic modalities affects genetic counseling and timely diagnosis. Effective genetic counseling should address to the patient's genetic background and ethical code. Access to appropriate and timely treatment of immunodeficiencies is scarce in some regions of the world. CONCLUSION High consanguinity rate and reduced access to prophylactic measures increase the burden of immunodeficiencies in many low- and medium-income countries. Furthermore, poor access to diagnostic and treatment modalities in these regions adversely affects patients' prognosis. Increased awareness among health care professionals and the public and increased collaboration with Western countries aid in diagnosis of these conditions. Further advancements require improved public funding to the prevention, diagnosis, and treatment of IEI.

Abstract
BACKGROUND Limited English proficiency (LEP) is associated with adverse clinical outcomes. The clinical impact of LEP in hematopoietic stem cell transplant (HSCT) has not been studied. The objectives of this study were to compare HSCT outcomes and health care utilization of Hispanic pediatric patients with and without parental LEP. METHODS We conducted a retrospective review of Hispanic/Latino pediatric patients receiving HSCT at a single institution. Families were identified as LEP or English proficient (EP) based on clinicians' notes, social work documentation, or the signature of a Spanish interpreter on treatment consents. RESULTS A total of 83 Hispanic/Latino patients were identified with 53 (65.1%) having parental LEP. More patients in the LEP group had a documented financial burden at pretransplant psychosocial evaluation (72.2% vs. 41.4%, p = .009). LEP patients were more likely to have health insurance coverage through government-sponsored Medicaid (76.9% vs. 27.6%, p < .001). LEP patients were hospitalized on average 13 days longer than EP patients, and LEP patients were more likely to have pretransplant cytomegalovirus (CMV) reactivity (67.3%) than EP patients (p = .001). Overall survival was lower in LEP than EP, but was not statistically significant (p = .193). Multivariable Cox modeling suggested a potentially higher risk of death in LEP versus EP (hazard ratio = 1.56, 95% CI: 0.38, 6.23). CONCLUSIONS Parental LEP in HSCT is associated with prolonged hospitalization and pretransplant CMV reactivity. These factors are associated with posttransplant complications and death. Our results suggest parental LEP is a risk factor for poor HSCT outcomes. Further study is warranted in a larger cohort.

Hematopoietic Cell Transplantation Outcomes among Medicaid and Privately Insured Patients with Sickle Cell Disease. Transplant Cell Ther 2021; 27:685.e1-685.e8. [PMID: 33895405 PMCID: PMC8680220 DOI: 10.1016/j.jtct.2021.04.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 03/23/2021] [Accepted: 04/13/2021] [Indexed: 10/21/2022]
Abstract
Compared with privately insured patients, recipients of Medicaid have been reported to have worse outcomes in several clinical conditions and following various surgical and medical procedures. However, the relationship between health insurance status and allogeneic hematopoietic cell transplantation (alloHCT) outcomes among patients with sickle cell disease (SCD) is not well described. We sought to compare alloHCT outcomes between patients with SCD who underwent alloHCT while enrolled on Medicaid versus those who underwent alloHCT while covered by private health insurance. We conducted a retrospective multicenter study using data reported to the Center for International Blood and Marrow Transplant Research. US patients enrolled on Medicaid or private insurance who underwent a first alloHCT for SCD between 2008 and 2018 were eligible for this study. The primary outcome was event-free survival (EFS), defined as time to death or graft failure. Secondary outcomes included overall survival (OS), graft failure, acute graft-versus-host disease (GVHD), and chronic GVHD. Univariate analysis was performed using the Kaplan-Meier method for EFS and OS. The proportion of patients with graft failure, acute GVHD, and/or chronic GVHD was calculated using the cumulative incidence estimator to accommodate competing risks (ie, death). Cox regression was used to identify factors associated with EFS, OS, graft failure, and acute and chronic GVHD. A total of 399 patients (Medicaid, n = 225; private insurance, n = 174) were included in this study. The median duration of follow-up was 34 months (range, 1.0 to 134.7 months) for the Medicaid group and 38.7 months (range, 0.3 to 139.3 months) for the private insurance group. Compared with the patients with private insurance, those on Medicaid had a significantly lower 3-year EFS (75.4% [95% confidence interval (CI), 69.4% to 81%] versus 82.2% [95% CI, 76.9% to 87.8%]; P = .0279) and a significantly higher 3-year cumulative incidence of graft failure (17.2% [95% CI, 12.5% to 22.5%] versus 10.5% [95% CI, 6.4% to 15.4%]; P = .0372). There were no significant between-group differences in 3-year OS (P = .6337) or in the cumulative incidence of acute GVHD (P = .4556) or chronic GVHD (P = .6878). Cox regression analysis after adjusting for other significant variables showed that the patients enrolled on Medicaid had a lower EFS (hazard ratio [HR], 2.36; 95% CI, 1.44 to 3.85; P = .0006) and a higher cumulative incidence of graft failure (HR, 2.57; 95% CI, 1.43 to 4.60; P = .0015), with no significant between-group differences in OS (HR, 0.99; 95% CI, 0.47 to 2.07; P = .9765), acute GVHD (HR, 0.94; 95% CI, 0.59 to 1.49; P = .7905), or cGVHD (HR, 0.98; 95% CI, 0.65 to 1.48; P = .9331). That EFS is worse in patients on Medicaid compared with privately insured individuals following alloHCT for SCD provides the rationale for research to better understand the mechanisms by which insurance status impacts alloHCT outcomes among patients with SCD.

Abstract
Preventing chronic graft-versus-host disease (GVHD) remains challenging because the unique cellular and molecular pathways that incite chronic GVHD are poorly understood. One major point of intervention for potential prevention of chronic GVHD occurs at the time of transplantation when acute donor anti-recipient immune responses first set the events in motion that result in chronic GVHD. After transplantation, additional insults causing tissue injury can incite aberrant immune responses and loss of tolerance, further contributing to chronic GVHD. Points of intervention are actively being identified so that chronic GVHD initiation pathways can be targeted without affecting immune function. The major objective in the field is to continue basic studies and to translate what is learned about etiopathology to develop targeted prevention strategies that decrease the risk of morbid chronic GVHD without increasing the risks of cancer relapse or infection. Development of strategies to predict the risk of developing debilitating or deadly chronic GVHD is a high research priority. This working group recommends further interrogation into the mechanisms underpinning chronic GVHD development, and we highlight considerations for future trial design in prevention trials.
